having issues with my painless harness. But not as bad as I have heard others having .... :/ anyways, today has not been painless at all and I am not sure where the problem is. Brake Lights don't work. Running lights do when I turn on headlights, blinker works. No Break lights. Here is what I have so far. manual location if anyone wants to look: https://www.painlessperformance.com/Manuals/20112.pdf Problem. Rear brake lights not working. Troubleshooting so far: 1. I closed circuit at the brake pedal switch. testing power at switch got light on probe.. working here. 2. 1 ft from fuse block, tested wire marked Brake light power #918 has power. (will come back to this wire for comments) 3. At 3 pin connector wire #918 has power to the pigtail that connects to tail harness. Page 114 in the manual says light blue #918 brake light power provides power to the brake lights on 1978-1981. other 2 wires going to this connector is Yellow and green Page 117: 1970-1973 tail harness power has 2 wires coming out of it. Yellow and gree. The blue cable does not connect to any cable on the tail harness. Turning on headlights, the tail light comes on. This is working. Blinker works. Brake lights do 'NOT' work. Reading page 114 again it references page 78 for the turn signal schematic. The turn signal #918 break switch output is wired correctly. I applied the brake and have power at both sides of the connector.... this is correct. And now I don't know what to do. I feel like the fuse box and harness is probably set up for 1977-1981 brake lights. I am very frustrated, I don't know if the harness is screwed from the factory, or if I am missing something. Any advice would be greatly appreciated on what to check next, or how to rewire to get this working correctly.
